SILVER BULLETS
Silver bullets have become an intergral part of werewolf mythology, which states that silver bullets are the only way to kill them. (Some myths also say that the bullet has to be engraved with the werewolf's name.) Well, at the very least, they're nice and shiny! Unlike with Vampires, werewolves can be shot in any vital organ (or other place that would kill them).
HOW TO USE
Well first of all you'd have to get a gun (a difficult thing to do in England), then you'd have to get the bullets especially made by a silversmith, it's all a lot of hassle. But if you do have these to hand, it's just a case of point and shoot, I suppose.
